My theory on what will happen.
Senpai will end up in a threesome with both Nanasawas at the same time.
Something (a kiss between the two Nanasawas, or both of them having an orgasm at the same time) will trigger the "spell" and the older one will be "absorbed" by the younger one. She and senpai will wonder what just happened and eventually continue their lives as a couple.
Meanwhile the older one will come back to her own time but in that timeline she and Senpai will be a couple, Senpai never got married and she is a kinda successful actress.
what do you think?
I don't know, but I think that would be sad for the senpai. Even though they are both the same person, she loves both of them separetely. Wouldn't the senpai be sad if the older Nanasawa disappeared?
I keep preaching that young MC goes with old MC and meets older senpai if this is indeed just like in Dragonball then older seto definetly needs some double love at this point!
Nah, older senpai will remember past with both MC's.
